Answer this question truthfully
### Question: Why is the procedure performed?
### Response: Arteries can become narrowed or blocked by deposits called plaque. Plaque is made up of fat and cholesterol that builds up on the inside of the artery walls. This condition is called atherosclerosis.
Percutaneous coronary intervention may be used to treat:
Blockage in a coronary artery during or after a heart attack Blockage of one or more coronary arteries that puts you at risk for a heart attack Persistent chest pain (angina) that medicines do not control
Not every blockage can be treated with percutaneous coronary intervention. Some patients who have several blockages or blockages in certain locations may need coronary bypass surgery.
